Problems solved by technology

[0005] Although the existing ceramic organic adhesive has so many advantages, the ceramic organic adhesive prepared by the existing preparation method also has poor impact resistance, is easy to be brittle, and causes shortcomings such as a large decrease in cohesive force. In the reaction process, the reaction is difficult to control. The violent combination will make the molecular weight of the adhesive too large and rigid, and the degree of polymerization is too small, which will make the viscosity insufficient and the impact resistance poor.

Abstract

The invention discloses a method for preparing an impact-resistant polyacrylate ceramic binder. The method comprises adding an initiator into a small amount of an organic solvent for full dissolutionto obtain an initiator solution, dividing the solution into 8 equal portions, adding the rest of the organic solvent into a reactor, carrying out condensation reflux, carrying out heating, adding methacrylic acid, isobornyl methacrylate and trimethylolpropane triacrylate into the solution, stirring the mixture for full dissolution, adding one equal portion of the initiator solution into the solution, adding one equal portion of the initiator solution into the mixed solution after an time interval, by parity of reasoning, adding the rest of the initiator solution into the mixed solution, wherein all the initiator solution is added in 140-210min, adding a coupling agent into the reactor, keeping the temperature, adding chlorosulfonated polyethylene and an ethylene-parathanoic acid-methyl methacrylate copolymer into the reactor, carrying out stirring and cooling, and adding a curing agent into the mixture to obtain the ceramic binder. Through modification with the ethylene-parathanoic acid-methyl methacrylate, the ceramic binder has very high bonding strength, strong impact resistance and good toughness.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a preparation method of an impact-resistant polyacrylate ceramic adhesive. Background technique [0002] Ceramic adhesive refers to an adhesive that can bond ceramics. Ceramic adhesives are generally divided into three categories: ceramic organic adhesives, ceramic inorganic adhesives, and metal powder adhesives. [0003] With the development of society, ceramic inorganic adhesives and metal powder adhesives are gradually eliminated by the market, while ceramic organic adhesives have been developed unprecedentedly. [0004] This is mainly because the existing ceramic organic adhesives have extremely strong cohesive force, which can be firm and strong without soaking bricks and wet walls, significantly improving work efficiency, convenient and quick construction, and excellent impermeability and anti-aging properties. Reduce the phenomenon of polluting finishes such as grout h...
